A schedule of plumbing fixtures and fixture fittings that will reduce the overall use of potable water within the building by 12% shall be provided. The reduction shall be based on the maximum allowable water use per plumbing fixture and fitting as required by the Los Angeles Building Standards Code in Article 1, Chapter IX of the LAMC.
A schedule of plumbing fixtures and fixture fittings that will reduce the overall use of potable water within the building by 20% shall be provided.
